I'm on the edge of buying an iPad 1G, the main reason is to keep my portfolio on it and to see my pictures instant. I was getting ready to buy it, but then I came across that in update 4.2 Apple lowered the USB output from 100mA to 20mA. And I'm not sure if my SD card uses more or less than 20mA..
Random quotes from the internet:
"Using my USB card reader a 1gb CF card worked fine but an 8gb one exceeded the power requirement."
I'm not sure if CF cards use more power than the SD cards, but other users state that their SD cards works just fine.
I'm currently using a SanDisk Extreme III 8GB.
And a quick bonus question: Will the iPad be able to read my CR2 files from my Canon 1000D (Also known as EOS Rebel XS)?
